Jaded vision Posted January 15, 2017 Share Posted January 15, 2017 Picked this up on a river bar north coast California. I read the rocks were formed during the tertiary, Cretaceous, and Jurassic time periods, hope that's useful information. I'll attach a couple more pics Link to comment Share on other sites More sharing options...

Ramon Posted January 15, 2017 Share Posted January 15, 2017 Looks like a rock. Also looks like bone because it has some cavities. I'll go with rock/ geological origin.

ynot Posted January 15, 2017 Share Posted January 15, 2017 I agree with a suggestive shaped rock. Tony Darwin said: " Man sprang from monkeys."

Vieira Posted January 16, 2017 Share Posted January 16, 2017 I agree, not a bone. Only a suggestive rock. Link to comment Share on other sites More sharing options...
